Abstract

Several agents can cause hemoparasitic diseases in dogs, and blood-sucking arthropods transmit these diseases. These agents can cause several clinical manifestations and, in some cases, can kill the host. Because these agents are essential in animal health, this study aims to detect the frequency of Ehrlichia canis, Rickettsia rickettsii, Anaplasma platys, and Rangelia vitalii by real-time PCR and Babesia vogeli in dogs in the southern region of the city of São Paulo, São Paulo. Of the 98 dog samples, 18 (18.4%) tested positive with real-time polymerase chain reaction for at least one studied agent. Of these 18 samples, 17 tested positive for a single agent (11.2% for B. canis vogeli, 1.02% for R. vitalii, and 5.1% for E. canis), and one showed co-infection with B. canis vogeli and R. vitalii. The results demonstrate the presence of hemoparasites in the studied animals, which can influence the quality and life expectancy of these animals. The Rangelia detection warns small animal clinicians to include it as a differential diagnosis for hemoparasitosis.
